Follow-up Comment #6, bug #38420 (project make):

In case anyone attempts to use the posted workaround, the calls to
variable_buffer_output can be interrupted which will set errno = EINTR.  When
this happens, gmake gets into a death spiral calling xrealloc, doubling the
amount of memory allocated repeatedly (which makes it impossible for the
process not to get interrupted by a child, setting errno = EINTR).
